Ellie is a board certified Physician Assistant and an affiliated member of both the California Academy of Physician Assistants (CAPA) and the American Academy of Physician Assistants (AAPA). She received her Masters in Physician Assistant Studies from Western University of Health Sciences in Pomona, California. Before joining West Coast Endocrine, Ellie had experience in both endocrinology and sleep medicine. She is a devoted and compassionate professional who prides herself in providing the time and attention needed for each individual patient. Education is an area in which she works to instill in her patients, since she instructs each patient about diabetes, its complications, and proper diet. "When someone is newly diagnosed with diabetes, he/she is experiencing an array of emotions and must have various questions running through his/her head. I am there to answer their questions and give them hope that he/she can live a long and healthy life with proper lifestyle modifications and treatment."

Ellie is also a certified insulin pump trainer, and can train patients on the continuous glucose monitoring system (CGMS). In fact, she was one of the first people to try the CGMS system when it was FDA approved. Her patience and understanding makes the patient comfortable with inserting an infusion or sensor site for the first time.


 

Sylvia Hernandez, RD, CDE

562-988-0040 | email

Sylvia is a Long Beach native with an interest in nutrition stemming from elementary school. "My sixth grade science experiment involved carbohydrate comparisons between various foods. I don't know if my classmates were particularly excited about it, but I sure was!" She pursued her nutrition degree at California State University, Los Angeles. She is a Certified Diabetes Educator and has a board certification specialty in diabetes. She holds membership with the Academy of Certified Diabetes Educators.

Throughout her years of practice, her best moments are "seeing the light bulb" go off. "It's a state of contentment for me when clients truly understand how nutrition impacts their health. Knowledge is one thing, but if you add doses of support and encouragement, they will do well." Mrs. Hernandez' experience in dealing with weight management issues of various degrees is extensive. "There are a number of social, emotional and behavioral aspects that need to be considered. The approach for helping someone lose weight may differ from person to person." Although her experience as a dietitian includes working in various hospital settings, consulting in a private practice, and lecturing for various programs, the message remains the same. "Long term behavior change is the goal... I'd like to help people in their journey to attain that."
